style="text-indent:25px">由于環(huán)境保護(hù)不斷推進(jìn)，對于地表水的監(jiān)測在地表水的環(huán)境保護(hù)建設(shè)中具有重要意義。相關(guān)的地表水監(jiān)測方法研究受到人們的極大重視。但是由于地表水具有流動性強的特點，導(dǎo)致地表水中的組分含量特征自動提取難度大。為了解決該問題，連續(xù)流動分析儀，設(shè)計了新的地表水監(jiān)測技術(shù)。構(gòu)建地表水監(jiān)測的全自動流動化學(xué)特征分析模型，提取全自動流動化學(xué)特征分析特征量，采用模糊信息檢測方法進(jìn)行地表水的組分含量特征檢測，結(jié)合組合型生態(tài)特征分析方法進(jìn)行地表水的連續(xù)流動分析，采用特殊浸潤性分析方法提取地表水的全自動流動分布特征量，通過液相反應(yīng)機制實現(xiàn)地表水監(jiān)測。采用連續(xù)流動分析儀能有效實現(xiàn)對地表水的化學(xué)成分特征監(jiān)測，提高了地表水的全自動流動化學(xué)成分分析能力，監(jiān)測結(jié)果準(zhǔn)確可靠，為地表水的利用和治理提供數(shù)據(jù)基礎(chǔ)。浙江流動注射分析儀可以定制嗎雙注樣法是利用雙通道同步注入閥將試樣溶液分別同時注入到兩種不同流路的載流中。</p><div

style="text-indent:25px">通常一套管線中載液和緩沖溶液的內(nèi)徑較粗,所受的影響也較大,也容易出現(xiàn)不同程度的阻塞。輸液管線聚四氟乙烯管內(nèi)徑非常小,十分硬,所以某一部分的小小彎折,都會造成阻塞,另外不同分析項目的反應(yīng)產(chǎn)物經(jīng)過長期積累,有時會產(chǎn)生微小的顆粒沉淀,阻塞管路的接口部分。因此二者在使用一段時間后要注意更換。較好的解決方法當(dāng)然是分析樣品的同時繪制樣準(zhǔn)曲線,以減少流速改變造成的系統(tǒng)誤差;無法每次曲線校準(zhǔn)的,也應(yīng)參照樣品的粗略范圍選擇兩個已知濃度的標(biāo)準(zhǔn)物質(zhì)作為質(zhì)控樣品同步分析,根據(jù)回收率作出以下判斷:回收率落在許可范圍內(nèi)的可根據(jù)樣品要求的分析精度選擇直接結(jié)果或進(jìn)行換算,回收率超出限定范圍的則須查明原因,及時更換管線并重新繪制校準(zhǔn)曲線。</p><p style="text-indent:25px">顯色劑流速減慢通常顯色劑是過量的,除非出現(xiàn)嚴(yán)重堵塞,否則一般不會影響檢測對象的生成,但顯色劑含量的減少間接提高了待測組分在反應(yīng)體系中的比例,易造成分析結(jié)果偏高。因為反應(yīng)全過程均在流動體系中進(jìn)行,所以流速就成為較重要的影響因素,阻塞也就成為較主要的故障(這里的阻塞包括流速的減緩、不暢和倒流)。試劑純度不夠、樣品溶液殘留懸浮顆粒物、可溶性金屬離子含量過高、反應(yīng)回路中使用聚乙烯管和聚四氟乙烯管使用一定時間后,都會影響流速,甚至造成堵塞。輸液管線聚乙烯管使用一段時間后,表面逐漸磨損、彈性逐漸喪失,管線與泵的接觸較以前減弱,作用于其上的壓力相應(yīng)減小。減小趨勢的不同步導(dǎo)致各管線流速變化的不均勻。流速的改變直接影響各試劑的擴散情況,導(dǎo)致試劑在混合樣品中所占比例發(fā)生變化,同等時間內(nèi)截取到的等量混合樣品中,其中待測組分的實際比例與校準(zhǔn)曲線的標(biāo)準(zhǔn)采集量不同,相當(dāng)于被人為地稀釋或富集,再按原有的線性關(guān)系進(jìn)行分析會有較大出入。流動分析儀可以能使較復(fù)雜的化學(xué)分析過程完全自動化。</p><div
